Prochlorperazine 10mg is a medication used to treat a variety of conditions, primarily related to nausea, vomiting, and certain types of dizziness or vertigo [1]. It is also used in the management of symptoms associated with schizophrenia [1].
How does Prochlorperazine work?
Prochlorperazine is a phenothiazine derivative. Its antiemetic (anti-nausea and vomiting) effects are believed to stem from its action on the chemoreceptor trigger zone (CTZ) in the brainstem, which plays a role in initiating the vomiting reflex [1]. It also has antipsychotic properties, thought to be related to its dopamine receptor blocking activity [1].
